This insulating kettle is tailored specifically for outdoor sports. The kettle with an arch design matches the waistline of people and fits well with the body. Meanwhile, such a design can reduce the burden while walking when the kettle is put into the bag. The compass on the cap can tell the direction to support outdoor sports lovers. The cap can be used as a cup. Its capacity of 100 ml is based on the amount of water needed by the body after exercise to promote the concept of healthy drinking. The small opening ensures a better insulation effect and the tap controls the flow of water to avoid spilling.
